E4440A trace data

I'm trying to retrieve data off of the E4440A as fast as I can. I configure the analyzer and the sweep time is about 2.6 seconds. When I read back the data it takes about 5.5 to 6 seconds to take a sweep and plot the data. It shouldn't be taking that long should it?

Is there a difference between similar settings with FFT off? Have you timed the trace capture vs plotting to see which one is taking the longest amount of time? Also, what are you using to program with (Matlab, VB, etc.)?

Thanks for the reply. It seems that there is some overhead time associated with the number of FFT points. When the number of FFT points was reduced from 11 to 1 the time to read back the data was about 4.2 seconds per sweep. Pretty much all of the delay comes from the read back of the data.
